Hi,
I've bought lumia520 last week, there some issues keep bothering me,
1. the battery backup- my daily usage is 2-3 hours playing music,videos & games, 30min. of browsing overall my usage is 4 hours per day, rest of the time it's idle. I charge it overnight, in the morning it shows 100%, i may play music for an hour in the mrng, i don't use it in work for 9hours, then in the evng for 1 hour for music, 20- 30min. games, 15mins. browsing at times playing youtube videos for 30mins. At end of the day battery goes to saver mode, showing critically low then i keep it for full charge overnight. Till now i'ven't made much phone call hardly 10-15 min. and no messeging. Battery is draining down fastly. My friend has a lumia510 his usage is more than mine he makes phone calls for 1 hour, plays music, games & browses net 2-3 hours but still his battery does not drain, his lasts for 2 days, if his usage is more it will come atleast for 1day and half or a day and he is using the phone since 4 months. If he listens music for an hour battery goes down by 2-3%, but in 520 it goes down by 10-15%. But, i'ven't used my lumia520 very much eventhough i need to keep it charging daily. The battery is draining very fast. Is there any problem with the battery should i need to replace the battery, or it's common for all Lumia520's or it's only in my phone. Does lumia510 has better battery backup than 520?
2. The time estimate shows different timing at every 10 mins. One time it shows Time estimate remaining 2 days, after 1 hour it shows 1 day other time it shows 7 hours, and another interesting thing i've noticed yesterday is, it showed time last charged 268 days 10 hours, after some time it showed 1 day 8 hours. There is something really going wrong, how can i set the time estimate correctly. My friend using L510 has not found any problem till now. Comparing to Lumia510 , 520 has better features and performance but i'm facing this battery draining fast. Please suggest is it problem with the phone or battery? Since i've purchased through online and still i've 20days of replacement guarantee, can my phone be replaced for my problem? If not phone may be replacement of the battery is it possible?
This is really worrying me since this is my first smatphone, I'm waiting for your suggestions, please do reply. Sorry for the long post.
